Abstract
Algae is an abundant and potential fermentation substrate. The enzymatic hydrolysis of algae was investigated by pre-treating an alkaline hydrogen peroxide with commercial cellulase and viscozyme. Algae used in this study was the Ulva pertusa. The evaluated response was the yield of released glucose after the enzymatic hydrolysis. Alkaline hydrogen peroxide containing mixtures of 1 wt% hydrogen peroxide and 1~1.75 wt% sodium hydroxide was also used. The results show that the highest glucose conversion was obtained for Ulva pertusa using 5 wt% hydrogen peroxide at $60^{\circ}C$ for 3 h. The required amount of enzymes after the pre-treatment with alkaline hydrogen peroxide were reduced by far compared to that of untreated Ulva pertusa. Also, the amount of glucose that is released during the enzymatic hydrolysis was increased.
